CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 339,517, dated April 6,1886.

Application filed August 18, 1885. Serial No. 174,746. (No model.)

is supported by the bail-rests a so that the end of the loop is on thesame horizontal plane as the shaft D, and so that the ends e come belowthe said horizontal plane. 55

lVhen two cars are brought together, the bail of one slips over the hailof the other, and the lowest bail than raises the one resting on it andstrikes against the draw-head of the opposite car. The arms d are turnedback- 60 ward until they strike against the stops a thus depressing theends e of the bail and raising its looped portion, so that it can throwthe opposite bail into a nearly vertical position, as shown in Fig. -1,and then slide upward 65 over the end of the opposite draw-head andengage with the shoulder a on the top of it and with the head of the pinwhich projects above the top of the said draw-head.

In order to uncouple cars, a spring-plate, 70 F, is provided andattached to the top of each draw-head. The pin passes through a slot,

f, in this plate, and the head of the said pin rests upon the draw-head.

G is a ring fastened to the plate F, for rais- 7 ing it, and therebydisengaging the loop of the bail from contact with the shoulder a andthe pin 0.

A chain, II, may be attached to ring G, so that the cars may beuncoupled from the roof; 80 or levers maybe pivoted to the ends of thecars, so that the uncoupling may be effected. from the sides.

In Fig. 4 I show the construction for automatically lowering the pin. Inthis construc- 8 5 tion a rod, I, is passed through the rear wall of thepocket 0, and bears a plate, I, at its forward end within the pocket.The rear end of this rod connects with the lower end of a lever, J,which is pivoted between its ends, 0 and is jointed at its upper end tothe pin-sup- To all whom it may concern:

Be it known that I, ALFRED D. BABCOCK, a citizen of the United States,residing at Leon, in the county of Cattaraugus and State of New 5 York,have invented certain new and useful Improvements in Car-Couplings, ofwhich the following is a description.

Figure l is a side view of the ends of two cars to which the coupling isattached, showing 10 them coupledtogether. Fig. Zisasideviewof one ofthe couplings, with portions of the end of the car shown in section.Fig. 3 is a plan view of one coupling, looking downward from above; andFig. 4 is a partial side and sectional View of one of the couplings,showing the trip for the pin.

This invention relates to car-couplings; and it consists in the detailedconstruction of the parts, hereinafter fully described, by which carsmaybe automatically coupled together,

and which may be used as a common. link-andpin coupling when only oneear is provided with the automatic device.

' In the accompanying drawings similar lot ters of reference indicatecorresponding parts in all the figures.

A are the draw-heads, which slide back and forth in suitable guidesattached to the framework of the cars, and are provided with buffer- 0springs B, or with other springs of the kind commonly in use for suchpurposes. Each draw-head is provided with a pocket, 0, in the front partof it, and with a pin, a, passing through holes in the end of thedraw-head, so

3 5 that two draw-heads can be united together by alink as commonlyemployed in car-couplings; or one of the draw-heads A may be coupled toany other kind of draw-head with which a common coupling will engage.The draw- 0 heads A are also each provided with the shout.

der a on top, with the stops a and a upon their sides, and withbail-rests a 1) is a short shaft pivoted in the sides of each draw-head,and provided with an arm, d, se-

5 curely fastened to each end of it, and with a spring, (2, inside thesaid draw-head. The spring (1 keeps the arms (1 pressing against thestops a on the draw-head.

E is the bail, consisting of a rod bent to form a loop, and providedwith ends 6, which are pivoted in the ends of the arms (1!. The bailporting plate F. By this construction the plate F, when raised, will beheld elevated by the lever J, and the plate I will be thrown forward inposition to be engaged by the link 9 5 in entering the pocket 0. Thelink engaging this plate will strike the plate I, force the same back,and so operate the lever, which will be moved so as to release the plateF, and the pin will descend into the pocket 0 and rest IOO through thelink.

Having thus described the invention, what is claimed as new, and isdesired to be secured by Letters Patent, is-

l. A car-coupling comprising a draw-bar having a hook andlateralshoulders a, a shaft journaled to said draw-bar and having crankarms d,and the bail supported on the outer ends of said arms and arranged torest on the shoulders of, substantially as set forth.

2. In a car-coupling, the combination of the draw-head A, provided withshoulder a, the stops a and a and the bail-rests a, the shaft D, havingthe spring (1 and arms d, and the bail E, provided with ends 0 andpivoted to the said arms, substantially as described and shown, and forthe purpose set forth.

3. In tear-coupling, the combination of the spring-plate F, providedwith aring and chain for raising it, the bail E, having ends e, the arms(I, the shaft D, provided with spring (1, and a draw-head, A, havingshoulder a, stops a and a", and the bail-rests (1 substantially asdescribed and shown, and for the purpose set forth.

4. Theimproved car-coupling,substantially as herein described and shown,consisting of ALFRED D. BABOOOK.
